Flashing what dose f4 mean it stuck on it and reset button keeps flashing

Turn off the phone and hold the volume up button and the home button together,then turn the phone on ( keep holding the volume up and home button ) when phone starts it will show you a secret menu, you can try rebooting it first from that menu and if it still dose not start do the same thing again but go for reset. ( this will wipe it clean,you will loose everything,so only do that as a last resort ) hope this helps

e-mail the company or the manufactor, maybe you might be able to have a new one.

e-mail the company or the manufactor they can help you.

The calculator OS has been upgraded to the version 2.53 MP.
For this version, whenever you remove batteries (or replace them) and turn calculator ON, you are reminded to Press [ALPHA][F1-F4] to locate Shortcuts Menu.
The calculator also asks the user to press either
[1:Do NOT show Again]
[2:Continue].

Here is what these cryptic messages mean.

Certain functions implemented on the new OS are available by pressing the [ALPHA] key followed by F1, F2, F3 or F4.
Since you may forget how to get to them, the calculator gently reminds you that there are other functions accessed only by pressing the [ALPHA] key.
It also gives you the option to flash the reminder every time the calculator memory is reset (CONTINUE) or NOT to SHOW the REMINDER again.

Usually after the RAM cleared message, press [2:Continue] or any other key but [1: ] to keep being reminded how to access the new functions.
Once a key is pressed the screen is cleared and you have the solid blinking cursor.

Explain what you mean when you say 'when i open the pc from main switch'.
Also, something you should try is updating the CMOS, or in other words flashing the BIOS firmware. Go to your motherboards manufacturers website and see if there are any BIOS updates for it.

Okay, ther manufacturer recommends unplugging the washer for at least 30 minutes to reset the computer. It could be you have a momentary glitch causing some problems. If you still have the same problem after leaving the washer unplugged, the following link explains the "FH" error code:
